wx 6t 3 m United States Patent Claims. (Cl. -16) This invention relates to improved pilaster structures and hinge bracket assemblies in which the door supporting hinge bracketsare rigidly secured to the jamb edge of the pilaster in cantilever suspension and without attachment to the side faces of the pilaster. This application is a continuation-in-part of my copending application Serial No. 696,864 filed November 15, 1957, now

US. Patent 2,876,874, issued March 10, 1959, and a division of my copending application Serial No. 795,683 filed February 26, 1959.

Hinge brackets made in accordance with this invention are particularly designed for cantilever attachment to frame structures, posts and pilasters whose jamb edge is of relatively narrow width, and are particularly designed for attachment to the jamb edge of hollow metal piiasters which measure only one to two inches or less in thickness, and which form the supporting uprights-for interior cubicles, such as toilet and hospital cubicles, and the like.

A typical hollow metal pilaster with which the hinge brackets of this invention may be associated, may be formed by a pair of spaced metal facing sheets bonded to a reinforcing core of sound deadening insulation, and which present paired inturned flanges along the exposed vertical and horizontal edges thereof. The paired inturned flanges present a pair of outturned lip portions formed integral therewith and joined together by exteriorly applied spot welds to provide a rigid pilaster construction. Edging strips of semi-tubular'cross section, and presenting a contoured facing portion and paired inturned lip portions, are telescoped over the outturned lip portions of the pilaster body to interlock therewith. The applied edging strips thus supply a finished appearance to the exposed vertical and horizontal edgesof the pilaster.

The improved hinge brackets of this invention may be die cast or otherwise formed as integral units to present a laterally extending door supporting arm section on which the door is swingably mounted. These hinge brackets are designed to be mounted on the jamb edge of a relatively thin pilaster by means which engage or interlock with a jamb portion of the pilaster or with associated parts applied to or built into the pilaster during its manufacture. Where the hinge bracket includes an exterior body section from which the arm supporting section laterally extends, the body section thereof is equipped with means to rigidly secure the same to a jamb edge seating face of the pilaster and between the terminal ends of the contoured jamb facing portions thereof, and with the exposed outer face of the bracket body section in contour symmetry with the outer faces of the contoured jamb facing portions of the pilaster.

The terminal ends of the bracket body section may be equipped with a pair of spaced tongues, wings or studs designed to telescope into the adjacent terminal ends bf slidable jarnb facing strips to thereby secure, or additionally secure, the hinge bracket in rigid cantilever suspension from the jamb face of the pilaster body.

As modified securing means, a locking channel may be secured to the fiat jamb portion of the pilaster body be- 3-,l@4,42'8 Patented Sept. 24, 1963 tween the terminal ends of the contoured jamb facing portions thereof, and which is designed to interlock with a corresponding female formation on the rear face of the bracket body section.

All forms of this invention feature hinge brackets which are in architectural symmetry and harmony with the adjacent contoured jamb facing sections of the pilaster body, and with the exposed portions of the hinge bracket confined to the jainb edge of the mounting pilaster. The laterally extending door supporting arm sections of these hinge brackets present a pintle hole formed to receive a hinge pintle associated with a bracket counterpart applied to either the upper portion or lower portion of the mounted door. By the use of these hinge brackets, the pilaster is not defaced by bracket side flanges which telescope over the sides of the pilaster and secured thereto by bolts or screws as heretofore used, but on the contrary, the exposed surfaces of these hinge brackets are contoured in blended symmetry with the jarnb edge of the pilaster-to provide a door supporting structure of architectural harmony and beauty.

These improved pilaster structures and hinge bracket assemblies are so constructed as to insure precise alignment of the upper and lower hinge brackets and accurate hanging of the door without field adjustment. These hinge brackets may be economically die cast or otherwise assembled as an integral unit at substantially less cost than door supporting hinge brackets heretofore made, can be attached to a' floor supported or ceiling hung pilaster during manufacture'thereof, and as mounted thereon, present an assembly which is substantiallyfree of projections and crevices lect.

All of the door supporting hinge brackets constructed in accordance with this invention are particularly designed for attachment to the jarnb edge of hollow metal posts or 'pilasters which may be either floor supported as shown in FIG. 1 or ceiling supported as shown in FIG. 2. These door supporting pilasters are particularly adapted for assembly into interior cubicles, such as hospital and toilet cubicles.

The floor supported pilaster 1 as shown in FIG. 1 and the ceiling hung pilaster 1' as shown in FIG. '2, and with which the door supporting hinge brackets of this invention are particularly adapted for attachment, comprise a pair of pilaster facing sheets 2-2 formed from sheet metal or other strong sheet material, which together present inturned flanges 3-3 along the exposed vertical and horizontal edges thereof. Each pair of inturned flanges 33 incorporate outturned lip portions 4 which are socured together bysuitable spot welds 4 exteriorly applied to the paired outturned lip portions at the crotch area between them as shown in FIG. 7. Prior to spot welding together the paired inturned lip portions 4 to provide a rigid pilaster construction, a reinforcing and insulating core 5 is first adhesively bonded to the inside face of one of the pilaster facing sheets 2, land the exposed face of the reinforcing core is then coated with adhesive and the other facing sheet 2 then applied thereto. Pressure is then applied to the sandwich as thus formed to insure a firm adhesive bond between the reinforcingcore 5 and the inside faces of the pilaster facing sheets 2-2. The reinforcing core 5 is desirably composed of a relatively hard, pilaster sheet bracing and sound deadeningv insulation packing, such as slabs of fibreglass, honeycomb fibreboard or other core material which is relatively light in weight, capable of deadening sound, and capable p of bracing and supporting the pilaster facing sheets 22 to which the reinforcing core 5 is adhesively bonded.

The exposed vertical and horizontal edges of the pilasters 11 are trimmed by means of edging strips 6 of semi-circular cross-section and similar in size and contour. Each edging strip 6 presents a face portion 6' of generally curvilinear form which terminates in inturned lip portions 7. The edging strips 6 are designed to be telescoped :longitudinally over the outturned lip portions 4 of the pilaster facing sheets 2-2, so that the inturned lip portions 7 of the edging strip will interlock with and be firmly secured to the outturned lip portions 4 of the pilaster facing sheets 2-2 as shown in FIGS. 1, 2, 7 and 8.

During manufacture of the sheet metal panel facing sheets 2-2 of the pilasters 1 and 1', suitable cut-outs, deformations or additions may be made in or to those areas of the intu-rned flanges 3 and outturned lip portions 4 to which the door supporting hinge brackets of this invention are to be applied, to thereby provide suitable seating faces and anchoring means for rigidly securing the selected hinge bracket to the jamb edge thereof, as more fully hereafter explained. All of the hinge brackets of this invention are particularly designed to be applied to the prepared areas of the inturned flanges 3 of the panel facing sheets 22, either before the lip portions 4 of the panel facing sheets have been spot welded together, or

after the reinforcing core 5 has been positioned between the panel facing sheets and the outturned lip portions 4 thereof welded together as heretofore explained.

The floor supported end of the pilaster 1 as shown in FIG. 1, and the ceiling supported end of the pilaster shown in FIG. 2, are suitably secured to the floor or ceiling wall by suitable brackets and lag bolts as shown in FIG. 2. The floor or ceiling supported end of the pilaster and associated wall securing means, are concealed within a trimming shoe 8 as shown in FIGS. 1 and 2 whichsnugly telescopes over the pilaster and snugly seats against the horizontal building wall to which the end of the supported pilaster is attached.

The upper door supporting hinge bracket A as shown in FIGS. 3 and 9 is designed for. attachment to the upper part of the door supporting pilaster 1 as shown in FIG. 1

or the upper part of the ceiling hung pilaster 1' shown I in FIG. 2. The lower door supporting hinge bracket A as shown in FIGS. 4 and 10 is designed for attachment to the lower part of the floor supported pilaster 1 shown in FIG. 1. Both of the door supporting hinge brackets A and A are generally similar in form and may be die cast as integral units. Each of the hinge brackets A and A presents a laterally extending arm section 20 integral with a vertically extending body section 21. The arm section 20 of the upper hinge bracket A has a pintle hole 20' therein designed to receive a pivot pintle associated with a bracket fixture (not shown) whichis attached to the upper part of the door to be mounted thereon. The laterally extending arm section 20 of the lower hinge bracket A has a pintle receiving hole 20" therein designed to receive and support a hinge pintle on which the bracket fixture (not shown) fixed to the lower part of the door is swingably mounted.

The body section 21 of the upper hinge bracket A as shown in FIGS. 3 and 9 and the lower hinge bracket A as shown in FIGS. 4 and 10, present a curvilinear outer face 21 which is contoured in conformity with the curvilinear outer face a of the adjacent edge moulding strips 6 which are applied to the pilaster body. The body section 21 presents square ends 22, and an anchor block 24 which projects from the rear thereof as shown in FIGS. 9 and 10. The anchor block 24- has a nose portion 25 which projects beyond the upper square end 22 of the body section as shown in FIGS. 3 and 4. The nose portion 25 has an inset abutment face 25 designed to abut against the inside face of the adjacent inturned flanges 3 of the pilaster body as shown in FIG. 11.

The body section 21 of each hinge bracket A and A also presents relatively flat rear seating face portions 22' extending along the sides of the anchor block 24 and designed to snugly seat against the outer faces of side iedge portions which define the sides of an anchor block receiving hole 16 cut in the inturned flanges 3 of the pilaster body. Each square end 22 of the body section 21 presents a pair of spaced insert studs 23 and 23 which extend vertically therefrom. Each insert stud 23 and 23' is tapered toward its free end, and the base thereof is generally triangular in cross section to thereby telescope into the adjacent interior corner of the edge moulding strip 6 as defined between the inside face of the curvilinear facing portion 6 and the inside face of the inturned dip portion 7 of the moulding strip 6 and the adjacent lip portion 4- of the pilaster.

In manufacturing the pilaster facing sheets 22 to form the pilaster 1-1 to which hinge brackets A and/ or A are to be applied, an appropriate cut-out is formed in the inturned flanges 3 thereof so that when the lip portions 4 of the pilaster facing sheets are welded together, an anchor block receiving hole 10 is formed therein as shown in FIG. 7, leaving side ledge portions ll) along the sides of the anchor block receiving hole It The outside faces of the side ledge portions ill provide seats for the rear seating face portions 22' of the body section 21 of the hinge brackets A and A. it will be noted that the outturned lip portions 44 of the pilaster facing sheets 22 are also cut away in forming the anchor block receiving hole 1i and that the terminal ends 4- of the lip portions 4- tenminate directly adjacent the upper and lower edges of the receiving hole 10.

The hinge brackets A and A are applied to the supporing pilaster structure formed as shown in FIG. 7, by tilting the anchoring block 2-4 thereof into the formed hole It so that the abutment face 25 of the nose portion 25 thereof will seat against the inside tfaces of the inturned flanges 3 directly above the formed hole it In the same tilting operation, the end portions of the relatively short upper studs 23 adjacent the abutment face 25' of the hinge brackets A and A, are also tilted under the adjacent terminal ends 4 of the flared lip portions 4 of the pilaster body and into bearing abutment against the inside faces the lip portions 4 the-reabove. Upon completion of the tilting operation, the side edges of the ledge portions 1% which define the hole 1%) will then be substantially in abutment with the adjacent sides on"; the anchor block 24, and with the rear face pontions 22 of the bracket body section 21 seating against the outside face of the pilaster edge portions 1%. It will be noted by referring to FIGS. 3, 4, 9 and 10 that the paired studs 23 extending from the lower end of the body section 21 of the hinge brackets A and A are longer and spaced slightly further apart than the paired studs 23 extending from the upper end of the body section 21. This permits the end portions of the paired insert studs 23 at the lower end of the body section 21 to be telescoped over the terminal ends 4" of the adjacent outturned lip portions 4 of the pilaster body and extend under the inner faces of the adjacent lip portions 4 extending downwardly therefrom. Upper and lower edge moulding strips 6 are then telescoped over the outt-urned lip portions 4 of the pilaster body until the terminal ends thereof abut the adjacent square ends 22 of the body section of the mounted hinge bracket, to thereby provide substantially flush and single line joints therebetween. It will be noted that the abutment face 25 of the nose portion 25 and the underface of the adjacent insert studs 23 are spaced apart for a distance slightly more than two thicknesses of sheet metal, to "thereby permit the adjacent terminal ends of the inturned flanges 3 of the pilaster body, and the adjacent terminal ends of the lip portions 7 of the edging strip, to telescope therebetween. The paired upper studs 23, which are of shorter length than the abutment face 25 of the nose portion 25 as shown in FIGS. 3 and 4, are

also in bracing abutment against the inner \face of the adjacent pilaster lip portions 4 which prevents lateral movement of the body section 21 of the hinge bracket A or .Ai'.

The =hin-ge brackets A and A are securely and rigidly anchored to the jamb edge of the pilastcr 1 or 1 by the nose pontion 25 whose inset abutment face 25 snugly abuts the inside rface of the adjacent terminal portions of the inturned flanges 3 of the pilaster body, and with the tlower end of the anchor block 24 seating on and supported by the adjacent horizontal edge of the pillaster flange portions 33 which defines the lower edge of the anchor block receiving hole 16, as shown in (FIG. 11. The hinge brackets AA are also braced by the rear seating race portions 22 of the bracket body section 21 which snugly seat against the outside races of the ledge portions id of the inturned flanges 3 which are adjacent the anchor block receiving hole 1i). The binge brackets A and A are additionally rigidly anchored by the paired insert studs 23 and 23 extending from both ends of the bracket body section 21 and project into the end Oif the adjacent semi-tubular edging strip 6 and thus locked in bracing relation against the inside face Olf the curvilinear facing p-ontion 6 of the edging strip 6 extending thereover, and the inside face of the adjacent underlying inturned lip pontions 7 of the edging strip 6, and the adjacent face of the outwardly flared lip portion 4 of the pilaster.

The door supporting hinge brackets A and A can be inexpensively made as integral castings, and when mounted on the jamb edge 0t the pilaster body as shown in FIGS. 1 and 2, are in streamline symmetry with the edging strips 6, and provide an assembled idoor supporting pilaster structure which is strong and rigid, long lasting in use, and is highly attractive and pleasing in architectural appearance.

The door supporting hinge bracket B as shown in FIGS. 5 and 12, is designed for attachment to the lower corner of a ceiling hung pilaster 1 as shown in FIG. 2. The hinge bracket B presents a door supporting arm section 2% extending laterally from its body section 21, the arm section 2i) having a hinge pintle receiving hoe 2h therein to which the lower end of binge pintle may be fixed and on which a suitable bracket fixture (not shown) attached to the lower end of the door may be s-wingably supponte d. The body section 21 of the hinge bracket B presents a curvilinear outer face 21' and a square out upper end 22. The body section 21 also has an anchoring block 24 projecting rearwardly theretfrorn and which presents a nose portion 25 extending from the upper end thereof which has an inset abutment face 25'.

The square cut upper end 22 of the hinge bracket B presents a pair of spaced insert studs 23 projecting vertically there'fnom. Its body section 21 also presents a pair of rear seating faces 22, extending along the sides of the anchor block 24, and which are designed to snugly seat against the outside faces of adjacent ledge portions ill, which extend along the ventical sides of an anchor block receiving hole 11, formed by cutting away inner parts of the vertically extending inturned flanges 3 at the lower end of the pilaster body, as shown in FIG. 13.

The hinge bracket B also features a wing section 26 as shown in FIGS. 5, 6 and 12 which extends rearwardly from the lower end of the anchor block 24. The wing section 26 has a curvilinear outer face 26' in shaped conformity to the curvilinear outer facing portion 6' of the edging strip 6 which extends along the lower horizontal edge of the ceiling hung pilaster 1 as shown in FIG. 6. The wing section 26 presents a square cut end 27 designed to snugly abut against the terminal end of the adjacent horizontal edging strip 6. The wing section 256 also presents a pair of spaced inner rail portions 23 designed to seat against the adjacent horizontal ledge portions 11" extending along the horizontal sides of the anchor block receiving hole 11, formed by cutting away inner parts of the horizontally extending inturned flanges 3 of the pilaster body as shown in FIG. 13. The inside face of the wing section 26 also presents a depressed center face 28 between the rail portions 28, in which the lower leg of a Tinnerrnan nut 12 may be pocketed as shown in FIG. 13. The lower hinge bracket B may be die cast from a suitable metal in integral form.

The lower corner of the ceiling hung pilaster 1 which is to receive the hinge bracket B, is formed as shown in FIG. 13 by cutting an angular shaped hole 11 in the lower ends of the vertical inturned flanges 3 and the adjacent ends of the horizontal inturned flanges 3 of the pilaster body, thereby leaving vertical side ledge portions 11' and horizontal side ledge portions 11". The vertically extending outturned lip portions 4 of the pilaster body terminate directly adjacent the upper transverse edge of the hole 11, and the horizontally extending outturned lip portions 4 terminate slightly short of the lower transverse edge of the hole 11, to thereby permit the telescopic application of a Tinnerman nut 12 over the hole defining transverse edges of the horizontal inturned flanges 3 as shown in FIG. 13.

The corner bracket B is applied to the pilaster body by tilting the anchoring block 24 thereof into the hole 11 of the pilaster body, with the abutment face 25' of its nose portion 25 in seating engagement against the adjacent inside faces of the vertical inturned flanges 3 adjacent the lower terminal ends thereof. As in the case of the hinge brackets A and A, above described, the abutment face 25 of the nose portion 25 of hinge bracket B and the adjacent insert studs 23, define a groove therebetween which receives the adjacent terminal ends of the inturned flanges 3 of the pilaster body and the terminal ends of the lip portions 7 of the edging strip 6. When the corner bracket B is tilted into position, the spaced studs are driven under the adjacent terminal ends 4" of the pilaster lip portions 4- and into bracing engagement therewith. The spaced side seating faces 22' of this bracket will then seat against the outside face of the vertically extending ledge portions 11' adjacent the hole. The spaced rail portions 28 of the rearwardly extending wing section 26 will then also seat against the outside face of the horizontally extending ledge portions 11" of the pilaster body, with the lower leg of the Tinnerman nut 12 pocketed within the depressed center face 28' of the wing section 26, as indicated in FIGS. 13 and 14. A metal securing screw 13 may then be applied to extend through the bracket wing section 26 and into the deformed hole of the Tinnerman nut 12 to further lock and secure the lower corner bracket B in rigid position.

When the lower corner bracket B is fully applied to the lower end of the ceiling hung pilaster 1' as shown in FIG. 2, the curvilinear face 21 of its body section 21 will be in streamlined symmetry with the curvilinear face 6' of the edge moulding strip 6 extending thereabove, and with the lower end of the vertically extending moulding strip 6 in abutting relation to the square cut end 22 of its body section 21. The paired insert studs 8 23 extending from the square cut end 22 will also be snugly pocketed within the inner corners of the lowerterminal end of the adjacent edging strip 6, and will also be positioned in bracing relation against the inside faces of the adjacent outturnedlip portions 4 of the pilaster body, with the edging strip 6 firmly locked to the pilaster body by the outturned lip portions 4 thereof.- The lower corner bracket B is additionally rigidlyfixed to the lower endof the ceiling hung pilaster 1' by the securing screw 13 which extends through the wing section 26 thereof and is screwed into the Tinnerman nut 12 clamped to the terminal ends of the horizontally extending inturned flanges 3 of the pilaster body.

The door supporting hinge bracket G shown in FIGS. 15, 17, 18 and 19, is designed to be mounted on the jamb face of the hollow metal pilaster 1 or 1' and to seat against the adjacent flange portions 17 of the pilaster body as shown in FIG. 16, and held'thereto by a snap fastener in the form of a snap lock channel 54. The hinge bracket G may be die cast as an integral unit to provide a door supporting arm section 26 extending from a body section 58 which presents a curvilinear outer face 50 in contour conformity to the outer faces of the curvilinear face portions 6 of the upper and lower edging strips 6 applied to the pilaster body. The hinge bracket G may be used as an upper hinge bracket, or a lower door supporting hinge bracket, by providing a pintle hole 29' therein to receive an upper door hinging pintle, or a pintle hole 2% therein which supports a lower pintle on which the door is swingably supported.

The bracket body section 50 may present square out ends 56" against which the terminal ends of the upper and lower edge moulding strips 6 are designed to abut, to thereby provide substantially flush and single line joints therebetween. The upper and lower ends of the body section 50 may also be provided wih a tongue or a pair of spaced vertically extending studs 51 at one or both ends thereof which are designed to telescope into the adjacent end of the semi-tubular edge moulding strip 6.

The body section 50 also presents a pair of spaced rear facing portions 52 which define a vertically extending locking groove 53 therebetween, as shown in FIGS. 15 and 19. The locking groove 53 presents side ledge portions 53' designed to interlock with a snap-lock channel 54 which is first applied to the jambface of the pilaster body as shown in FIG. 16. The spaced rear facing por-tions'52 of the bracket body section 50 are designed to flatly seat against the outside faces of the inturned flange portions 17 of the pilaster body when the bracket body section 50 has been pushed into locking relation with the snap-lock channel 54.

The snap-lock channel 54 presents a web portion 54' which seats against the outside faces of the inturned flange portions 17 of the pil aster body. The, snap-lock channel 54 also presents side flanges 54" terminating in resilient curvilinear rim portions 54" designed to snap into interlocking engagement with the sideledge portions 53' of the locking groove 53 formed in the rear face of the bracket body section '50. The web portion 5 of the snaplock channel 54 is rigidly secured to an internal bracing plate 18 which seats against the inside faces of the inturned flange portions 17 of the pilaster body as shown in FIG. 16, and is secured thereto by suitable metal screws 18'.

In manufacturing the pilasters 1 and 1' to support one or more of the hinge brackets G, the inturned flanges 3 of the pilaster facing sheets 2-2 are formed to provide the usual out-turned lip portions 4 above and below the area Where the hinge bracket G is to be applied, leav ing lipless inturned flange portions 17 therebetween' which provide a flat seat for the spaced seating portions 52 of the bracket body section 56). A sturdy bracing plate 18 is positioned adjacent the inside face of the inturned flange portion 17 of one of the pilaster fa ing sheets and secured as by spot welds 17 thereto. After the reinforcing core has been adhesively bonded to this pilaster facing sheet 2, the companion pilaster facing sheet 2 is applied thereover and adhesively bonded to the adjacent face of the reinforcing core 5. The inturned lip portions 4 are then secured together by the application of a series of spot WCldS 4' in the crotch there-between as shown in FIG. 16. The terminal ends 4 of the existing lip portions 4 are suificientiy spaced to permit the application of the body section 5-3 of the hinge bracket G to the inturned flange portions 17 there'oetween. The inturned flange portions 17 of the second and companion pilaster facing sheet 2 may also be spot Welded or screwed to the underlying bracing plate 18. The snaplock channel 54 is then placed in seating position against the outside faces of the flange portions 17, and rigidly held in position by two or more metal screws 18 extending through the web portion 54 thereof and screwed into tapped holes provided in the internal reinforcing plate is.

The bracket body section 54 is then applied by telescoping the lock'ng groove 54- in the rear face thereof over the side flange portions 54" of the snap-lock channel 54 until the resilient curvilinear rim portions 54" thereof snap into interlocking engagement with the side ledge portions 53 of the locking groove. The spaced rear facing portions '52 of the body section will then snugly seat against the outside faces of the inturned flange portions 17 of the pilaster body. In applying the bracket body section 59 to the snap lock channel 54, one end of the body section 5%} is first telescoped over the side flange portions 54" of the snap lock channel 54 and the adjacent paired studs 51 telescoped under the adjacent terminal ends 4" of the pilaster li-p portions 4. The paired studs at the other end of the body section will then clear the adjacent terminal ends 4 of the pilaster lip portions 4 therebelow, when the body section 59 is fully telescoped into locking engagement with the entire length of the side flange portions 54" of the snap-lock channel $4.

The body section 5-3 of the hinge bracket may then be vertically adjusted so that the paired studs 51 at both ends thereof will underlie and abut against the inner faces of both the upper and lower set of pilaster lip portions 4.

The upper and lower moulding strips 6 are then telescoped over the outwardly flared lip portions 4 of the pilaster body as indicated in FIG. 15, and the terminal ends thereof placed in abutting relation to the square cut ends 5%" of the bracket body section 5d, and with the locking studs 51 snugly telescoped into the adjacent terminal end portion of the semi-tubular edging strip 54 and in abutting relation to the inner faces of the outwardly flared lip portions 4 extending above and below the body section of this hinge bracket.

The hinge bracket G is thus rigidly and securely mounted on the jamb face of the pilaster by the snap-lock channel 54 whose resilient curvilinear rim portions 54' are in locking engagement with the side ledge portions 53' of the locking groove 53 extending vertically along the rear face of the bracket body section 5%. This bracket is further braced by the spaced rear facing por tions 52 extending along the locking groove 53, and which snugly seat against the outside faces of the inturned flange portions 17 of the pilaster body. The hinge bracket G may be further rigidly fixed to the jamb face of the pilaster body by the provision of tongues or studs 51 which project from the upper and lower ends of the bracket body section 5%} and into the end of the adjacent semi-tubular edging strip 6, and with the three sides of each stud 51 in bracing relation to the inside faces of the curvilinear portion 6 and the inturn'ed lip portion 7 of the edging strip 6, and the face or edge of the adjacent lip portion 4 of the pilaster.

As thus assembled, the curvilinear outer face 5d of the bracket body section 55} is in streamlined symmetry lb with the outer curvilinear faces of the applied edging strips 6, with no bivacket securing means exteriorly visible when the hinge bracket G is fully assembled on its supporting pil aster.

The spaced insert studs 23 associated with the brackets A, A and B, and the similar insert studs 51 associated with hinge bracket G, provide a particularly effective means for rigidly securing these hinge brackets to the jamb portion of the pilaster, since these spaced insert studs telescope into the adjacent terminal end of the semitubular edge moulding strip 6 between the curvilinear facing portion 6 and inturned lip portions 7 thereof and thus are firmly locked thereto. These spaced insert studs permit extension of the terminal ends of the adjacent outwardly flared lip portions 4 of the pilaster body, to a point directly adjacent the end of the bracket body section, so the terminal end of the edge moulding strip is locked to the outturned lip portions 4 directly adjacent the terminal end of the bracket body section.

It will be particularly noted that all of the hinge brackets of this invention are directly supported from the jamb portion of a pilaster body, and do not overlap the side panel facing sheets of the pilaster body, and are particularly designed to be rigidly secured to the jamb edge portion of relatively thin pilaster bodies which may measure only one inch in thickness. hinge and pilaster structures of this invention present an assembly wherein the exterior faces of the hinge brackets are in contoured symmetry with the exposed faces of the pilaster edge moulding-strips 6, and as assembled, present fine line butt joints therebetween which are scarcely discernible, and wherein the hinge bracket is securely locked and held in fixed position by internal locking elements, and/ or by the use of insert studs, which project from one or both ends of the bracket and which snugly telescope into the adjacent terminal end of a slidable semi-tubular edging strip.

Pilaster structures and binge bracket assemblies made in accordance with this invention feature the elimination of bracket side flanges and other projections heretofore used to secure the hinge bracket to the pilaster, and which provide areas for the collection of dirt and foreign matter which cannot be readily removed. The hingel brackets of this invention can. be cast or formed in one piece, at substantially less cost than door supporting hinge brackets heretofore made and used, and can be mounted on the jamb edge of the pilaster at the factory in precise door supporting alignment, and with less labor and less cost than the pilaster and hingev bracket asse blies heretofore made and used. The necessary modifications to the jamb edge of the pilaster bodies, can be accomplished in accordance with this invention at minimum cost when cutting and fabricating the panel facing sheets, or during assembly of the pilas-ter body.

While certain novel features of this invention have been disclosed herein and are pointed out in the claims, it will be understood that various omissions, substitutions, and changes maybe made by those skilled in the art without departing from the spirit of this invention.
